DETAILED DESCRIPTION

The description that follows includes systems, methods, techniques,instruction sequences, and computing machine program products thatembody illustrative embodiments of the disclosure, in the followingdescription, for the purposes of explanation, numerous specific detailsare set forth in order to provide an understanding of variousembodiments. It will be evident, however, to those skilled in the art,that embodiments may be practiced without these specific details. Ingeneral, well-known instruction instances, protocols, structures, andtechniques are not necessarily shown in detail.

Often, users consume media content, and specifically videos, on theirmobile device. Users are always seeking new ways to discover content.Sometimes users generate content using predefined graphics or audiocontent. In certain cases, users may be interested in finding suchcontent that was generated using the predefined graphics or audiocontent. In order to do so, the users have to manually search throughand view various content submitted by other users and manually determinewhether such content includes the predefined graphics or audio content.This task is extremely burdensome and time consuming which ends upfrustrating users and wasting device resources.

The disclosed embodiments improve the efficiency of using the electronicdevice by providing a system that automatically organizes content basedon themes used to generate the content. Specifically, the disclosedsystem allows a user to browse through content on the basis of whethersuch content was generated using a predefined content item generationtemplate. For example, a content item generation template that isassociated instructions for generating a content item is identified anda messaging application displays an identifier of the content itemgeneration template. The messaging application receives input thatselects the identifier of the content item generation template andretrieves a plurality of content items associated with the content itemgeneration template. Each of the plurality of content items has beenpreviously generated by a respective user of a plurality of users of themessaging application in accordance with the instructions associatedwith the content item generation template. The messaging applicationdisplays the retrieved plurality of content items associated with thecontent item generation template.

According to example embodiments, there is provided a challengemechanism (or mechanic) for a messaging system, according to which usersof the messaging system are enabled to create and submit content (e.g.,user generated content (UGC) such as photographs or video), to themessaging system having a specific annotation or supplementation (e,g,,an image overlay or full site) corresponding to a particular challengetheme (e.g., a content item generation template). These user generatedcontent collections may relate to any one of a number of differentevents or themes, such as music, social events, holidays, comedy, phoneetc. While example embodiments discussed herein are discussed withrespect to a musical theme, it will be appreciated that challenges(content item generation templates) may be applied with respect to anumber of different themes. The challenge mechanic seeks to drive userengagement with the messaging system, and also to expand creativeexpression, for example by facilitating the convenient and automatedgeneration of content (e.g., UGC). In some embodiments, the messagingsystem allows users to view UGC that was generated for a particulartheme or according to instructions of a particular content itemgeneration template.

In this way, the disclosed embodiments improve the efficiency of usingthe electronic device by reducing the complexity a user experiences infinding certain content that is of interest to the user, and by reducingthe number of screens and interfaces a user has to navigate through tofind such content. This reduces the device resources (e.g., processorcycles, memory, and power usage) needed to accomplish a task with thedevice.

FIG. 1 is a block diagram showing an example messaging system 100 forexchanging data (e.g., messages and associated content) over a network106. The messaging system 100 includes multiple client devices 102, eachof which hosts a number of applications, including a messaging clientapplication 104 and a third-party application 105. Each messaging clientapplication 104 is communicatively coupled to other instances of themessaging client application 104, the third-party application 105, and amessaging server system 108 via a network 106 (e.g., the Internet).

Accordingly, each messaging client application 104 and third-partyapplication 105 is able to communicate and exchange data with anothermessaging client application 104 and third-party application(s) 105 andwith the messaging server system 108 via the network 106. The dataexchanged between messaging client applications 104, third-partyapplications 105, and the messaging server system 108 includes functions(e.g., commands to invoke functions) and payload data (e.g., text,audio, video, or other multimedia data). Any disclosed communicationsbetween the messaging client application 104 and the third-partyapplication(s) 105 can be transmitted directly from the messaging clientapplication 104 to the third-party application(s) 105 and/or indirectly(e.g., via one or more servers) from the messaging client application104 to the third-party application(s) 105.

The third-party application(s) 105 and the messaging client application104 are applications that include a set of functions that allow theclient device 102 to access a content item generation template system124. The third-party application 105 is an application that is separateand distinct from the messaging client application 104. The third-partyapplication(s) 105 are downloaded and installed by the client device 102separately from the messaging client application 104. In someimplementations, the third-party application(s) 105 are downloaded andinstalled by the client device 102 before or after the messaging clientapplication 104 is downloaded and installed. The third-party application105 is an application that is provided by an entity or organization thatis different from the entity or organization that provides the messagingclient application 104. The third-party application 105 is anapplication that can be accessed by a client device 102 using separatelogin credentials than the messaging client application 104. Namely, thethird-party application 105 can maintain a first user account and themessaging client application 104 can maintain a second user account. Forexample, the third-party application 105 can be a social networkingapplication, a dating application, a ride or car sharing application, ashopping application, a trading application, a gaming application, or animaging application.

In some embodiments, the messaging client application 104 provides auser with a graphical user interface that allows the user to search forcontent that corresponds to a particular content item generationtemplate and/or submit content generated using instructions of thecontent item generation template. For example, the messaging clientapplication 104 may present a graphical user interface with anidentifier of a content item generation template (also referred to as achallenge or lens challenge). The content item generation template maybe created by an artist or producer and may have one or more augmentedreality content (e.g., music, videos, graphical element(s), text, andthe like) associated with it. The content item generation templateincludes a set of instructions that are presented to a user forgenerating content according to a theme of the content item generationtemplate.

For example, when the content item generation template is accessed, thecontent item generation template starts playing a song and allows theuser to capture a video or record audio together with or in replacementof a portion of the song. The user can use a slice tool provided by themessaging client application 104 to select a portion of the song that isincluded in the content item generation template over which the user'svoice or audio is recorded. Specifically, the content item generationtemplate may include a three minute song and the user can select asegment between the time points 1:30 (min:sec) and 1:45 (min:sec) of thesong to be replaced by the user's personal audio recording.

As another example, the content item generation template may includeaugmented reality content that represents a particular scene.Specifically, the content item generation template may include one ormore graphical elements that look like the Academy Awards (e.g., astage, a podium, a screen and audience). The content item generationtemplate may include instructions for the user to capture a video of theuser making a speech at the Academy Awards. The video including theuser's face is overlaid or combined with the graphical elements andspecifically behind the podium. In this way, the content item the usergenerates looks like the user is making a speech at the Academy Awards.

As another example, the content item generation template may include amusical composition that is combined with one or more graphicalelements. The graphical elements are time stamped such that a differentone of the graphical elements is presented on the screen at differenttime points in the musical composition. The content item generationtemplate may instruct the user to capture video of the user while themusical composition is played and while the graphical elements arepresented. For example, the user can sing lyrics corresponding to themusical composition and graphical elements may be overlaid on top of theuser singing the lyrics in correspondence with different portions of themusical composition.

Once the user is satisfied with the content item the user generatesaccording to the content item generation template, the messaging clientapplication 104 allows the user to submit the generated content to oneor more designated friends or recipients and/or to be shared as part ofall the content items associated with the content item generationtemplate. For example, the messaging client application 104 provides afirst option for the user to share the generated content item with oneor more friends and provides a second option for the user to enableaccess to the generated user generated content item by any user of themessaging client application 104 who selects an identifier of thecontent item generation template. Namely, selection of the second optionadds the content item generated by the user to the collection of UGCthat is associated with the given content item generation template.

In some embodiments, the instructions of the content item generationtemplate presented to the user for generating a content item are onlyincluded and presented to the user while the content item is beinggenerated. After the content item is generated and shared with otherusers, the instructions are removed or not displayed with the contentitem. For example, the content item generation template may overlayinstructions over a video feed being captured by the user. Theinstructions may instruct the user to perform some action (e.g., singlyrics, position a camera a certain way, or make a dance move). Theinstructions, in some cases, may include text of lyrics of a song thatis associated with the content item generation template. After the usercompletes capturing the video according to the displayed instructions,the video is stored without the instructions. Namely, another user whoviews or accesses the video that was created by the user while theinstructions were presented may see the video without seeing theinstructions. For example, the content item generation template mayoverlay lyrics of a song for a user to sing while capturing audio orvideo of the user. After the audio or video is captured, the lyrics areremoved from the video and/or are not stored as part of the video. Inthis way, another user does not see the lyrics being presented whileviewing the video or audio of the user singing the lyrics of the song.

In some embodiments, the messaging client application 104 receives auser input selecting an identifier of a given content item generationtemplate. Specifically, the messaging client application 104 presents alist of different content item generation templates. The list may bevertically oriented or horizontally oriented. The user can browse thelist by swiping left/right (for horizontally oriented lists) or up/down(for vertically oriented lists). Once the user finds a content itemgeneration template that is of interest, the user can tap on theidentifier of the content item generation template. In response, themessaging client application 104 may present a set of UGC that wasgenerated according to the instructions of the selected content itemgeneration template.

In some embodiments, the set of UGC that is presented corresponding tothe selected content item generation template may be ranked. In someimplementations, the set of UGC is ranked based on attributes of theuser viewing the set of UGC and a set of attributes of the users whocreated the UGC. For example, the UGC may be ranked and sorted based ona geographical region of the user who is viewing the UGC and thegeographical region of the users who created the UGC. Specifically, ifthe user is in California, the messaging client application 104 maypresent a set of UGC that was generated according to the instructions ofthe content item generation template from users in California. In someimplementations, the UGC is ranked based on a relationship between theuser who submitted the UGC and the user who is viewing the UGC. Forexample, a piece of UGC that is generated by the user's friend may bepositioned higher or earlier in the set of UGC than another piece of UGCthat was generated by a user who is not a friend. In someimplementations, the set of UGC is ranked based on a number of contentitems that are associated with the content item generation template.

In some embodiments, the set of UGC is ranked based on a combination ofmoderator input and engagement signals. For example, the set of UGC isranked based on whether a moderator assigned a high or low rank to agiven one of the UGC items and at least one of a number of times thegiven content item has been viewed by users of the messaging clientapplication 104, length of time the users spend viewing the givencontent item, a geographical location of the users who view the givencontent item, or how recently the given content item was received.

The messaging server system 108 provides server-side functionality viathe network 106 to a particular messaging client application 104. Whilecertain functions of the messaging system 100 are described herein asbeing performed by either a messaging client application 104 or by themessaging server system 108, it will be appreciated that the location ofcertain functionality either within the messaging client application 104or the messaging server system 108 is a design choice. For example, itmay be technically preferable to initially deploy certain technology andfunctionality within the messaging server system 108, but to latermigrate this technology and functionality to the messaging clientapplication 104 where a client device 102 has a sufficient processingcapacity.

The messaging server system 108 supports various services and operationsthat are provided to the messaging client application 104. Suchoperations include transmitting data to, receiving data from, andprocessing data generated by the messaging client application 104. Thisdata may include message content, client device information, geolocationinformation, media annotation and overlays, virtual objects, messagecontent persistence conditions, social network information, and liveevent information, as examples. Data exchanges within the messagingsystem 100 are invoked and controlled through functions available viauser interfaces (UIs) of the messaging client application 104.

Turning now specifically to the messaging server system 108, an APIserver 110 is coupled to, and provides a programmatic interface to, anapplication server 112. The application server 112 is communicativelycoupled to a database server 118, which facilitates access to a database120 in which is stored data associated with messages processed by theapplication server 112.

Dealing specifically with the API server 110, this API server 110receives and transmits message data (e,g., commands and messagepayloads) between the client device 102 and the application server 112.Specifically, the API server 110 provides a set of interfaces (e.g.,routines and protocols) that can be called or queried by the messagingclient application 104 and the third-party application 105 in order toinvoke functionality of the application server 112. The API server 110exposes various functions supported by the application server 112,including account registration; login functionality; the sending ofmessages, via the application server 112, from a particular messagingclient application 104 to another messaging client application 104 orthird-party application 105; the sending of media files (e.g., images orvideo) from a messaging client application 104 to the messaging serverapplication 114, and for possible access by another messaging clientapplication 104 or third-party application 105; the setting of acollection of media data (e.g., story); the retrieval of suchcollections; the retrieval of a list of friends of a user of a clientdevice 102; the retrieval of messages and content; the adding anddeleting of friends to a socialgraph; the location of friends within asocial graph; access to user conversation data; access to avatarinformation stored on messaging server system 108; and opening anapplication event (e.g., relating to the messaging client application104).

The application server 112 hosts a number of applications andsubsystems, including a messaging server application 114, an imageprocessing system 116, a social network system 122, and the content itemgeneration template system 124. The messaging server application 114implements a number of message processing technologies and functions,particularly related to the aggregation and other processing of content(e.g., textual and multimedia content) included in messages receivedfrom multiple instances of the messaging client application 104. As willbe described in further detail, the text and media content from multiplesources may be aggregated into collections of content (e.g., calledstories or galleries). These collections are then made available, by themessaging server application 114, to the messaging client application104. Other processor- and memory-intensive processing of data may alsobe performed server-side by the messaging server application 114, inview of the hardware requirements for such processing.

The application server 112 also includes an image processing system 116that is dedicated to performing various image processing operations,typically with respect to images or video received within the payload ofa message at the messaging server application 114. A portion of theimage processing system 116 may also be implemented by the content itemgeneration template system 124.

The social network system 122 supports various social networkimgfunctions and services and makes these functions and services availableto the messaging server application 114. To this end, the social networksystem 122 maintains and accesses an entity graph within the database120. Examples of functions and services supported by the social networksystem 122 include the identification of other users of the messagingsystem 100 with which a particular user has relationships or is“following” and also the identification of other entities and interestsof a particular user. Such other users may be referred to as the user'sfriends. Social network system 122 may access location informationassociated with each of the user's friends to determine where they liveor are currently located geographically. Social network system 122 maymaintain a location profile for each of the user's friends indicatingthe geographical location where the user's friends live.

The content item generation template system 124 allows users to view,browse, search for, and submit content items associated with one or morecontent item generation templates. The content item generation templatesystem 124 allows an artist or producer to create and submit a contentitem generation template. For example, the artist or producer mayprovide an identifier including a graphical representation (e.g., coverart) of the content item generation template. The artist or producer mayalso input various parameters of the content item generation templateincluding one or more of a period of time during which content will becollected from users, one or more conditions for ending collection ofcontent, a name of the user generated content collection, an image to bedisplayed when a user views the user generated content collection, amusic or video asset to present as part of generating the content item,and a trigger to modify one or more graphics presented during generationof the content item according to designated time points.

After receiving the content item veneration template from the artist orproducer, the content item generation template system 124 adds thereceived identifier to a list of content item generation templatespresented to a user of the messaging client application 104. The contentitem generation template system 124 may allow users to join or submitcontent to the content item generation template and/or view contentpreviously submitted for the content item generation template. Thecontent item generation template system 124 automatically ranks thecontent items submitted for a given content item generation templateaccording to one or more criteria.

The application server 112 is communicatively coupled to a databaseserver 118, which facilitates access to a database 120 in which isstored data associated with messages processed by the messaging serverapplication 114. Database 120 may be a third-party database. Forexample, the application server 112 may be associated with a firstentity, and the database 120 or a portion of the database 120 may beassociated with and hosted by a second, different entity. In someimplementations, database 120 stores user data that the first entitycollects about various each of the users of a service provided by thefirst entity. For example, the user data includes user names, passwords,addresses, friends, activity information, preferences, videos or contentconsumed by the user, and so forth.

FIG. 2 is a schematic diagram 200 illustrating data, which may be storedin the database 120 of the messaging server system 108, according tocertain example embodiments. While the content of the database 120 isshown to comprise a number of tables, it will be appreciated that thedata could be stored in other types of data structures (e.g., as anobject-oriented database

The database 120 includes message data stored within a message table214. An entity table 202 stores entity data, including an entity graph204. Entities for which records are maintained within the entity table202 may include individuals, corporate entities, organizations, objects,places, events, and so forth. Regardless of type, any entity regardingwhich the messaging server system 108 stores data may be a recognizedentity. Each entity is provided with a unique identifier, as well as anentity type identifier (not shown).

The entity graph 204 stores information regarding relationships andassociations between entities. Such relationships may be social,professional (e.g., work at a common corporation or organization),interest-based, or activity-based, merely for example.

Message table 214 may store a collection of conversations between a userand one or more friends or entities. Message table 214 may includevarious attributes of each conversation, such as the list ofparticipants, the size of the conversation (e.g., number of users and/ornumber of messages), the chat color of the conversation, a uniqueidentifier for the conversation, and any other conversation relatedfeature(s).

The database 120 also stores annotation data, in the example form offilters, in an annotation table 212. Database 120 also stores annotatedcontent received in the annotation table 212. Filters for which data isstored within the annotation table 212 are associated with and appliedto videos (for which data is stored in a video table 210) and/or images(for which data is stored in an image table 208). Filters, in oneexample, are overlays that are displayed as overlaid on an image orvideo during presentation to a recipient user. Filters may be of varioustypes, including user-selected filters from a gallery of filterspresented to a sending user by the messaging client application 104 whenthe sending user is composing a message. Other types of filters includegeolocation filters (also known as geo-filters), which may be presentedto a sending user based on geographic location. For example, geolocationfilters specific to a neighborhood or special location may be presentedwithin a 1.11 by the messaging client application 104, based ongeolocation information determined by a Global Positioning System (GPS)unit of the client device 102. Another type of filter is a data filter,which may be selectively presented to a sending user by the messagingclient application 104, based on other inputs or information gathered bythe client device 102 during the message creation process. Examples ofdata filters include current temperature at a specific location, acurrent speed at which a sending user is traveling, battery life for aclient device 102, or the current time.

Other annotation data that may be stored within the image table 208 isso-called “lens” data. A “lens” may be a real-time special effect andsound that may be added to an image or a video.

As mentioned above, the video table 210 stores video data which, in oneembodiment, is associated with messages for which records are maintainedwithin the message table 214. Similarly, the image table 208 storesimage data associated with messages for which message data is stored inthe entity table 202. The entity table 202 may associate variousannotations from the annotation table 212 with various images and videosstored in the image table 208 and the video table 210.

Content item generation template(s) 207 stores one or more content itemgeneration templates. Each of the content item generation template(s)207 is associated with a particular theme. Namely, each of the contentitem generation template(s) 207 includes a different set of instructionsand/or augmented reality content that is presented to assist users togenerate content corresponding to the theme of the content itemgeneration template 207. As an example, a music theme based content itemgeneration template 207 may present a musical composition to the userand/or lyrics corresponding to the musical composition. The music themebased content item generation template 207 may instruct the user to singone or more of the presented lyrics and automatically records video ofthe user singing the lyrics. In some cases, the music theme basedcontent item generation template 207 may present audio of the musicalcomposition and the singer and presents a slicer tool that allows theuser to designate one or more portions for which to replace the singer'svoice with the user's voice.

A story table 206 stores data regarding collections of messages andassociated image, video, or audio data, which are compiled into acollection (e.g., a story or a gallery). The creation of a particularcollection may be initiated by a particular user (e.g., each user forwhich a record is maintained in the entity table 202). A user may createa “personal story” in the form of a collection of content that has beencreated and sent/broadcast by that user. To this end, the U1 of themessaging client application 104 may include an icon that isuser-selectable to enable a sending user to add specific content to hisor her personal story.

A collection may also constitute a “live story,” which is a collectionof content from multiple users that is created manually, automatically,or using a combination of manual and automatic techniques. For example,a “live story” may constitute a curated stream of user-submitted contentfrom various locations and events. Users whose client devices 102 havelocation services enabled and are at a common location event at aparticular time may, for example, be presented with an option, via a UIof the messaging client application 104, to contribute content to aparticular live story. The live story may be identified to the user bythe messaging client application 104 based on his or her location. Theend result is a “live story” told from a community perspective.

A further type of content collection is known as a “location story,”which enables a user whose client device 102 is located within aspecific geographic location (e.g., on a college or university campus)to contribute to a particular collection. In some embodiments, acontribution to a location story may require a second degree ofauthentication to verify that the end user belongs to a specificorganization or other entity (e.g., is a student on the universitycampus).

FIG. 3 is a schematic diagram illustrating a structure of a message 300,according to some embodiments, generated by a messaging clientapplication 104 for communication to a further messaging clientapplication 104 or the messaging server application 114. The content ofa particular message 300 is used to populate the message table 214stored within the database 120, accessible by the messaging serverapplication 114. Similarly, the content of a message 300 is stored inmemory as “in-transit” or “in-flight” data of the client device 102 orthe application server 112. The message 300 is shown to include thefollowing components:

-   -   A message identifier 302: a unique identifier that identifies        the message 300.    -   A message text payload 304: text, to be generated by a user via        a UI of the client device 102 and that is included in the        message 300.    -   A message image payload 306: image data, captured by a camera        component of a client device 102 or retrieved from memory of a        client device 102, and that is included in the message 300.    -   A message video payload 308: video data, captured by a camera        component or retrieved from a memory component of the client        device 102 and that is included in the message 300.    -   A message audio payload 310: audio data, captured by a        microphone or retrieved from the memory component of the client        device 102, and that is included in the message 300.    -   Message annotations 312: annotation data (e.g., filters,        stickers, or other enhancements) that represents annotations to        be applied to message image payload 306, message video payload        308, or message audio payload 310 of the message 300.    -   A message duration parameter 314: parameter value indicating, in        seconds, the amount of time for which content of the message        (e.g., the message image payload 306, message video payload 308,        message audio payload 310) is to be presented or made accessible        to a user via the messaging client application 104.    -   A message geolocation parameter 316: geolocation data (e.g.,        latitudinal and longitudinal coordinates) associated with the        content payload of the message. Multiple message geolocation        parameter 316 values may be included in the payload, with each        of these parameter values being associated with respect to        content items included in the content (e.g., a specific image        within the message image payload 306, or a specific video in the        message video payload 308).    -   A message story identifier 318: identifier value identifying one        or more content collections (e.g., “stories”) with which a        particular content item in the message image payload 306 of the        message 300 is associated. For example, multiple images within        the message image payload 306 may each be associated with        multiple content collections using identifier values.    -   A message tag 320: each message 300 may be tagged with multiple        tags, each of which is indicative of the subject matter of        content included in the message payload. For example, where a        particular image included in the message image payload 306        depicts an animal (e.g., a lion), a tag value may be included        within the message tag 320 that is indicative of the relevant        animal. Tag values may be generated manually, based on user        input, or may be automatically generated using, for example,        image recognition.    -   A message sender identifier 322: an identifier (e.g., a        messaging system identifier, email address, or device        identifier) indicative of a user of the client device 102 on        which the message 300 was generated and from which the message        300 was sent.    -   A message receiver identifier 324: an identifier (e.g., a        messaging system identifier, email address, or device        identifier) indicative of user(s) of the client device 102 to        which the message 300 is addressed. In the case of a        conversation between multiple users, the identifier may indicate        each user involved in the conversation.

The contents (e.g., values) of the various components of message 300 maybe pointers to locations in tables within which content data values arestored. For example, an image value in the message image payload 306 maybe a pointer to (or address of) a location within an image table 208.Similarly, values within the message video payload 308 may point to datastored within a video table 210, values stored within the messageannotations 312 may point to data stored in an annotation table 212,values stored within the message story identifier 318 may point to datastored in a story table 206, and values stored within the message senderidentifier 322 and the message receiver identifier 324 may point to userrecords stored within an entity table 202.

FIG. 4 is a block diagram showing an example content item generationtemplate system 124, according to example embodiments. Content itemgeneration template system 124 includes a content item templategeneration module 412, a content item template generation identificationmodule 414, a content item generation module 416, and a content itemranking module 418.

Content item template generation module 412 allows an artist or producerto create and/or submit a content item generation template 124. Theartist or producer logs into the content item generation template system124 to establish a first authentication session using authenticationcredentials of the artist or producer. In some implementations, thefirst authentication session includes administrative privileges to thecontent item generation template submitted by the artist or producerassociated with the authentication credentials. The content itemtemplate generation module 412 displays a configuration user interfacein the first authentication session that allows the artist or producerto provide input parameters for defining the instructions associatedwith the content item generation template submitted by the artist orproducer.

For example, the content item template generation module 412 presents agraphical user interface that allows the artist or producer to upload agraphical representation of the content item generation template and oneor more of a period of time during which content will be collected fromusers, one or more conditions for ending collection of content, a nameof the user generated content collection, an image to be displayed whena user views the user generated content collection, a music or videoasset to present as part of generating the content item, and a triggerto modify one or more graphics presented during generation of thecontent item according to designated time points. Specifically, theartist or producer may upload a song for the content item generationtemplate and lyrics of the song. As another example, the artist orproducer may upload a song with instructions for the user to perform oneor more actions during one or more portions of the song while the songis played back on a user device.

In some cases, the artist or producer may only allow content to begenerated and submitted to the collection associated with the contentitem generation template during a period of time (e.g., between a starttime and an end time). When the identifier of the content itemgeneration template is presented before or after the period of time,selection of the identifier may inform the user about the details of theinstructions associated with the template but may not allow the user toactivate and generate content using the template. When the identifier ofthe content item generation template is presented to a user during theperiod of time, the user can select an option to join or submit contentto be associated with the template. In response to selection of theoption, the content item generation template is activated and launchedtogether with a camera feed of the user device. The user can view theinstructions of the template and create content using the camera feed tobe shared with other users. In some embodiments, when the identifier ofthe content item generation template is presented to a user during theperiod of time, the user can select the identifier to view contentsubmitted by other users using the template.

In some cases, the artist or producer may only allow content to begenerated and submitted to the collection when conditions are satisfied.For example, the conditions may specify a maximum number of contentitems to be created. Once the maximum number is reached, selection ofthe identifier may inform the user about the details of the instructionsassociated with the template but may not allow the user to activate andgenerate content using the template. Before the maximum is reached, theuser can select an option to join or submit content to be associatedwith the template.

After the artist or producer completes creating and submitting thecontent item generation template, the content item template generationmodule 412 stores the content item generation template as part of thecontent item generation template(s) 207.

Content item template generation identification module 414 presents tousers of the messaging client application 104 content item generationtemplates stored in the content item generation template(s) 207. In someembodiments, the content item template generation identification module414 sorts the templates that are presented to a user in a list based onpopularity, age of the template, size, number of content items submittedto the given template, or other suitable criteria. For example, thecontent item template generation identification module 414 may determinethat a first content item generation template is associated with 50content items that were previously generated by users using the firstcontent item generation template. The content item template generationidentification module 414 may determine that a second content itemgeneration template is associated with 80 content items that werepreviously generated by users using the first content item generationtemplate. In such cases, the content item template generationidentification module 414 may position the second content itemgeneration template earlier in the list than the first content itemgeneration template.

In some cases, the content item template generation identificationmodule 414 may rank the templates using weighted attributes. Forexample, a popularity attribute may be associated with a higher weightthan number of content items attribute. In such cases, the first contentitem generation template, which may be more popular than the secondcontent item generation template, may be ranked higher and positionedearlier in the list than the second content item generation templateeven though the second content item generation template is associatedwith a greater number of content items than the first content itemgeneration template.

The content item template generation identification module 414 presentsthe list of content item generation templates to a user of the messagingclient application 104. The list of content item generation templatesmay be presented in a dedicated portion of the display while othercontent items organized by other criteria are presented in otherportions of the display. Each content item generation template isrepresented in the list by an identifier that indicates the theme of thetemplate, the artist or producer of the template, and that includesoptions for submitting content to the template. For example, a givencontent item generation template may include an option to join thetemplate when an insufficient number of content items (e.g., contentitems less than a threshold) (or no content items) have previously beencreated and submitted by other users using the content item generationtemplate. The join option may be selected by the user to activate thecontent item generation template and a camera feed of the user device tocreate content using the template. In some embodiments, any content itemgeneration template that is included in the list may be removed at anytime if a popularity of the content item generation template falls belowa threshold, or if the content item generation template reaches acertain age.

In other cases, when a threshold number of content items have beenpreviously created and submitted by other users using the content itemgeneration template, the identifier may include a representation of thenumber of content items that are associated with the template. Selectionof the number may present to the user a list of the previously generatedcontent that was generated using the template by other users. While theuser is browsing or viewing the list, the user can tap a camera icon toautomatically launch and activate the template to generate content usingthe content item generation template.

In response to receiving a user selection of an identifier of a contentitem generation template, the content item template generationidentification module 414 retrieves the instructions of the templatefrom content item generation template(s) 207. The instructions mayinclude any augmented reality content associated with the template. Thecontent item template generation identification module 414 provides theinstructions and the identified template to the content item generationmodule 416. Content item generation module 416 launches and activatesthe template and activates a camera feed of the user device to allow theuser to generate a content item corresponding to the selected contentitem generation template.

In some embodiments, the augmented reality content associated with thetemplate and instructions are automatically presented and launched oncethe content item generation module 416 activates the template and thecamera feed. For example, the content item generation module 416 mayautomatically start presenting a video feed being captured by the frontor rear-facing camera of the user device. The instructions of thetemplate may indicate whether the front or rear-facing camera of theuser device should be activated. The content item generation module 416may start playing back a music composition or track that is associatedwith the template and may present lyrics according to the time stamps ofthe lyrics and the music track. The content item generation module 416may also automatically begin storing the video feed being captured. Oncethe music composition ends, the content item generation module 416 maystop storing the video feed and present options for the user to modifythe captured video and/or share the captured video with designedrecipients and/or to associate the video with the selected content itemgeneration template.

In some embodiments, the content item generation module 416 may startpresenting a video feed from the front or rear-facing camera of the userdevice and may present an identifier of the activated template. Thecontent item generation module 416 may await user confirmation beforestarting to present the instructions and/or augmented reality contentassociated with the content item generation template. For example, afterthe user selects a start option on the screen, then the content itemgeneration module 416 may begin playing back a music composition ortrack that is associated with the template and may present lyricsaccording to the time stamps of the lyrics and the music track. Thecontent item generation module 416 may also begin storing the video feedbeing captured. Once the music composition ends, the content itemgeneration module 416 may stop storing the video feed and presentoptions for the user to modify the captured video and/or share thecaptured video with designed recipients and/or to associate the videowith the selected content item generation template.

In some embodiments, according to the template instructions, the contentitem generation module 416 may present one or more graphical elements atdifferent time points within a given interval of time. For example, thecontent item generation module 416 may present a first graphical elementat a first time point and a second graphical element at a second timepoint. The content item generation module 416 may capture the video feedbeing received from the front or rear-facing camera and combine thecaptured feed with the presented graphical elements. The content itemgeneration module 416 may display instructions for the user to performone or more actions while, before or after the graphical elements arepresented. The actions may be captured by the camera feed and at the endof the interval of time, the content item generation module 416 maypresent options for the user to share the captured video. In someembodiments, the instructions are only included and displayed to theuser while capturing the video and are not included in the video that iscaptured and shared with other users. Namely, the user may see theinstructions to perform a sequence of actions being displayed on thescreen while the video is being captured but after the video is capturedand stored, the video of the user performing the actions is shared withother users without displaying the instructions to the other users.

In some embodiments, the content item ranking module 418 receives avideo that is generated using a given content item generation template.The content item ranking module 418 presents the video to a moderator.The moderator provides input that confirms that the video matches atheme of the template and depicts content corresponding to theinstructions of the template. The moderator then assigns a manual rank(e.g., high or low rank) to the video and adds the video to a collectionof content items associated with the given content item generationtemplate.

The content item ranking module 418 analyzes various engagement factorsfor each content item in the collection associated with the givencontent item generation template. The content item ranking module 418combines the engagement factors with the manually assigned rank of eachcontent item to generate a rank for each content item. The content itemranking module 418 sorts the content items in the collection associatedwith the given content item generation template according to theassigned ranks. In some cases, the engagement factors depend on the userwho is requesting to view a given collection. In such cases, thecollection of content items presented to a first user may be rankeddifferently and ordered differently than the same collection of contentitems presented to a second user. For example, the first user in a firstgeographical region may see the collection of content items ordereddifferently and ranked differently than the second user in a secondgeographical region.

As another example, the content item ranking module 418 assigns agreater rank and weight to content items submitted by a user's friendsthan content items submitted by other users of the messaging clientapplication 104. This way, a given user sees content items generatedusing a given content item generation template that were submitted bythe given user's friends before content items submitted by other users.In some implementations, a threshold number (e.g., 10) of the mostpopular content items from popular user accounts are presented at andranked higher than all other content items in a collection of contentitems associated with a given content item generation template.Specifically, the content item ranking module 418 retrieves anidentifier of each user who submits a given content item to a collectionof content items associated with the content item generation template.The content item ranking module 418 determines popularity of the userswho submitted content items by looking at how active the user is on themessaging client application 104, the number of followers the user has,and/or the number of friends of the user. The content item rankingmodule 418 ranks content items of users who have a popularity ratingthat exceeds a given threshold, higher than other users who have a lowerpopularity rating. In addition, the content item ranking module 418presents a representation (e.g., a name or avatar) of such users whohave been determined to be popular and who submitted the content itemsto the collection for the content item generation template.

FIGS. 7A-C includes illustrative inputs and outputs of the content itemgeneration template system 124, according to example embodiments. Thecontent item generation template system 124 may present a graphical userinterface 710 on a messaging client application 104. The graphical userinterface 710 may include a first region 711 dedicated to presenting alist of identifiers of content item generation templates. The graphicaluser interface 710 may include one or more additional regions dedicatedto presenting content items corresponding to different categories.

The first region 711 may present a horizontal list of identifiers ofdifferent content item generation templates. The user can swipeleft/right to navigate through the list of content item generationtemplates. A first content item generation template 716 may graphicallyrepresent a theme associated with the first content item generationtemplate 716. The first content item generation template 716 may displayan album cover or other identifier of the artist who provided orgenerated the first content item generation template 716. Each templateidentifier in the first region 711 may include a symbol 712 thatspecifically indicates that the template is a content item generationtemplate. This symbol helps the user distinguish between content itemgeneration templates and other types of augmented reality content that auser can use to generate content.

The content item generation template system 124 may present a join nowoption 714 in the first content item generation template 716 to allow auser to submit content or generate content according to the instructionsof the first content item generation template 716. In some embodiments,the join now option 714 is presented only if the content item generationtemplate system 124 determines that less than a threshold number ofcontent items have been submitted and created by users for the firstcontent item generation template 716. Namely, the content itemgeneration template system 124 may count how many content items areassociated with the first content item generation template 716 and mayretrieve a threshold number associated with the first content itemgeneration template 716. If the number of content items associated withthe first content item generation template 716 is less than theretrieved threshold number, the content item generation template system124 presents the join now option 714. If the number of content itemsassociated with the first content item generation template 716 isgreater than or equal to the retrieved threshold number, the contentitem generation template system 124 presents the number of content items731 in a graphical user interface 730 (FIG. 7B).

In some embodiments, the form and format of the number of content item731 may depend on the quantity of content items. For example, if thenumber of content items is between 999-99999, the full number ispresented with a comma (e.g., 26368 is presented as 26,368). If thenumber of content items is between 100000-999999, one decimal point isshown for the thousands place and a K is added (e.g., 782345 ispresented as 782.3K). If the number of content items is greater than1000000, two decimals are shown for the hundred thousands and thousandsplace and an M is added (e.g., 4568097 is presented as 4.57M).

The user can tap anywhere within the displayed identifier of the firstcontent item generation template 716 but not on the join now option 714to view additional details about the template. For example, if the usertaps on the region in which a title of the first content item generationtemplate 716 is displayed, the content item generation template system124 presents a graphical user interface 720. Graphical user interface720 provides a detailed description or summary of the instructionsassociated with the first content item generation template 716.Graphical user interface 720 includes a join option to allow the user tosubmit content or generate content according to the instructions of thefirst content item veneration template 716.

In some cases, selection of the join option may automatically activatethe template and a camera feed of the user device. Once the template isactivated, instructions of the template are presented to the user (e.g.,lyrics of a song) and the camera feed begins being captured and stored.In some implementations, selection of the join option, launches a camerafeed and a summary of the selected content item generation template. Theuser can select a launch or start option to see the instructions for thetemplate and/or begin capturing a video according to the augmentedreality content of the template.

In some embodiments, the content item generation template system 124 maydetermine that less than a threshold number of content items havepreviously been generated according to the first content item generationtemplate 716. In such cases, the content item generation template system124 may present an alert to the user or prompt or message indicating tothe user that the user can be the first person to generate contentaccording to the first content item generation template 716. The promptor message may include a join option to allow the user to submit contentor generate content according to the instructions of the first contentitem generation template 716.

In graphical user interface 730, if the user taps or selects the numberof content items 731 that is shown in the identifier of the firstcontent item generation template 716, the content item generationtemplate system 124 presents the user with graphical user interface 740.Graphical user interface 740 includes a region 741 in which a set orcollection of identifiers of content items associated with the firstcontent item generation template 716 is presented. In some embodiments,a given one of the identifiers of the content items includes arepresentation 743 of the user who submitted or generated the givencontent item associated with the identifier. The representation 743 maybe an avatar or picture of the user. In some cases, the graphical userinterface 730 may only present representations 743 for users who havebeen determined by the content item ranking module 418 to be popular.For example, the content item ranking module 418 determines popularityof the users who submitted content items by looking at how active theuser is on the messaging client application 104, the number of followersthe user has, and/or the number of friends of the user. The content itemranking module 418 ranks content items of users who have a popularityrating that exceeds a given threshold, higher than other users who havea lower popularity rating. As a result, the content items of the popularusers are presented at the top of the collection of content items ingraphical user interface 730. In addition, the representation 743 (e.g.,a name or avatar) of such users who have been determined to be popularand who submitted the content items to the collection for the contentitem generation template are included for the identifiers of the contentitems submitted by the popular users but the representation 743 is notincluded for content items submitted by non-popular users.

The user can select any of the identifiers of the content items to viewor playback the content item associated with the selected identifierthat was generated using the first content item generation template 716.In some embodiments, after selecting a first identifier of the contentitem associated with the first content item generation template 716, thecontent item generation template system 124 presents the videoassociated with the selected first identifier. When playback of thevideo completes, the content item generation template system 124automatically retrieves and plays back the next video associated withthe next identifier in the set or collection of identifiers. In somecases, when playback of the video completes, the content item generationtemplate system 124 returns the user to the graphical user interface 730in which the collection or set of identifiers of the content itemsassociated with the first content item generation template 716 ispresented.

In some embodiments, the set or collection of identifiers of contentitems associated with the first content item generation template 716 isranked according to one or more factors. For example, the set orcollection of identifiers of content items associated with the firstcontent item generation template 716 is ranked based on an orderdetermined by the content item ranking module 418.

The graphical user interface 740 includes a camera option 742. Thecamera option 742 is overlaid on top of a portion of the set orcollection of identifiers of content items associated with the firstcontent item generation template 716. In response to receiving a userselection of the camera option 742, the content item generation templatesystem 124 retrieves the instructions corresponding to the first contentitem generation template 716 and activates the template. Specifically,in response to receiving the user selection of the camera option 742,the content item generation template system 124 presents the user with acamera feed in the graphical user interface screen 750 and/or presentsinstructions corresponding to the first content item generation template716 for which the content items are presented in graphical userinterface, 740. The camera option 742 allows the user to join orgenerate content, using the first content item generation template 716,for submission to the collection and/or to share with one or moredesignated recipients.

In some implementations, the first content item generation template 716includes a music track. In such cases, in response to receiving a userselection of the camera option 742, the content item generation templatesystem 124 presents a graphical user interface screen 750. Graphicaluser interface screen 750 presents an image of the artist who createdthe template and the song. The content item generation template system124 does not launch a camera feed or activate the camera in this case.The content item generation template system 124 begins playing back themusic track associated with the first content item generation template716. The music track includes a vocal portion and an instrumentalportion. The content item generation template system 124 presents aslicer tool 752 to allow the user to select a specific portion of themusic track. The user can then replace the vocal portion but not theinstrumental portion in the selected portion of the music track with anaudio recording of the user's voice. Once the user completes recordingover the music track, an option is presented to the user allowing theuser to share the content item with one or more designated recipientsand/or to add the content item to the collection of content itemsassociated with the first content item generation template 716. In somecases, an icon 754 providing attribution to the artist is generated inresponse to the user recording over a portion of the music track. Thisicon 754 may be moved around the screen and placed on other contentitems (e.g., images or videos) captured by the user but may not beremoved. In some implementations, the user can add other graphicalelements or content items to the content item that the user created withthe music track.

In some embodiments, after a user creates a content item using a contentitem generation template, the content item generation template system124 presents a graphical user interface screen 760. The graphical userinterface screen 760 includes one or more options for allowing the userto share the content item with other users of the messaging clientapplication 104. For example, the graphical user interface screen 760includes a first option 761 that represents the first content itemgeneration template 716. The first option 761 may describe the firstcontent item generation template 716 and include a title and/orgraphical image of the template. The user can check or uncheck (selector deselect) the first option 761 to add or exclude submission of thecontent item to the collection of content items associated with thefirst content item generation template 716. In some embodiments, if acontent item is added to the first content item generation template 716,any user of the messaging client application 104 is allowed and canaccess the content item. The user can also select one or more friends inthe graphical user interface screen 760 to whom to send the contentitem. After the user selects or deselects the first option 761 and/orspecifies one or more friends in graphical user interface screen 760,the user can select the send option 762. In response to receiving a userselection of the send option 762, the content item generation templatesystem 124 automatically and simultaneously sends the content item tothe one or more friends who the user selected and/or adds the contentitem to the collection of content items associated with the firstcontent item generation template 716 (if the first option 761 wasselected).

In some embodiments, the content item generation template system 124presents a graphical user interface screen 770 in response to receivinga user request to access a profile of the user. The graphical userinterface screen 770 includes a list of content items the user hasshared with other users. The graphical user interface screen 770includes a dedicated portion 771 that presents a collection of contentitems associated with a particular content item generation template. Thededicated portion 771 only presents the collection of content itemsassociated with a content item generation template to which the user haspreviously added a content item. For example, content item generationtemplate system 124 may include first and second content item generationtemplates. The content item generation template system 124 may determinethat the user has previously selected an identifier of the first contentitem generation template 716, generated content item using the firstcontent item generation template 716, and added the content item to thefirst content item generation template 716 (e.g., by selecting firstoption 761). In response, the content item generation template system124 may add the first content item generation template 716 informationto the dedicated potion 771. In response to determining that the userdid not select or add content items to the second content itemgeneration template, the content item generation template system 124 mayexclude the second content item generation template information from thededicated portion 771.

In some embodiments, the user may add a particular content itemgeneration template to a favorites list without adding a content item toa collection associated with the particular content item generationtemplate. In such cases, the particular content item generation templatethat has been added to a favorites list is also included in thededicated potion 771. In some embodiments, each content item generationtemplate that is listed in dedicated potion 771 includes a list ofidentifiers of content items that are in a collection associated withthe corresponding content item generation template. The list ofidentifiers is selectable such that any given identifier can be selectedto view or access the corresponding content item in the collection.

FIG. 8 is a block diagram illustrating an example software architecture806, which may be used in conjunction with various hardwarearchitectures herein described, FIG. 8 is a non-limiting example of asoftware architecture and it will be appreciated that many otherarchitectures may be implemented to facilitate the functionalitydescribed herein. The software architecture 806 may execute on hardwaresuch as machine 900 of FIG. 9 that includes, among other things,processors 904, memory 914, and input/output (I/O) components 918. Arepresentative hardware layer 852 is illustrated and can represent, forexample, the machine 900 of FIG. 9. The representative hardware layer852 includes a processing unit 854 having associated executableinstructions 804. Executable instructions 804 represent the executableinstructions of the software architecture 806, including implementationof the methods, components, and so forth described herein. The hardwarelayer 852 also includes memory and/or storage modules memory/storage856, which also have executable instructions 804. The hardware layer 852may also comprise other hardware 858.

In the example architecture of FIG. 8, the software architecture 806 maybe conceptualized as a stack of layers where each layer providesparticular functionality. For example, the software architecture 806 mayinclude layers such as an operating system 802, libraries 820,frameworks/middleware 818, applications 816, and a presentation layer814. Operationally, the applications 816 and/or other components withinthe layers may invoke API calls 808 through the software stack andreceive messages 812 in response to the API calls 808. The layersillustrated are representative in nature and not all softwarearchitectures have all layers. For example, some mobile orspecial-purpose operating systems may not provide aframeworks/middleware 818, while others may provide such a layer. Othersoftware architectures may include additional or different layers.

The operating system 802 may manage hardware resources and providecommon services. The operating system 802 may include, for example, akernel 822, services 824, and drivers 826. The kernel 822 may act as anabstraction layer between the hardware and the other software layers.For example, the kernel 822 may be responsible for memory management,processor management (e.g., scheduling), component management,networking, security settings, and so on. The services 824 may provideother common services for the other software layers. The drivers 826 areresponsible for controlling or interfacing with the underlying hardware.For instance, the drivers 826 include display drivers, camera drivers,Bluetooth® drivers, flash memory drivers, serial communication drivers(e.g., Universal Serial Bus (USB) drivers), Wi-Fi® drivers, audiodrivers, power management drivers, and so forth depending on thehardware configuration.

The libraries 820 provide a common infrastructure that is used by theapplications 816 and/or other components and/or layers. The libraries820 provide functionality that allows other software components toperform tasks in an easier fashion than to interface directly with theunderlying operating system 802 functionality (e.g., kernel 822,services 824 and/or drivers 826). The libraries 820 may include systemlibraries 844 (e.g., C standard library) that may provide functions suchas memory allocation functions, string manipulation functions,mathematical functions, and the like. In addition, the libraries 820 mayinclude API libraries 846 such as media libraries (e.g., libraries tosupport presentation and manipulation of various media format such asMPEG4, H.264, MP3, AAC, AMR, JPG, PNG), graphics libraries (e.g., anOpenGL framework that may be used to render two-dimensional andthree-dimensional in a graphic content on a display), database libraries(e.g., SQL-ite that may provide various relational database functions),web libraries (e.g., WebKit that may provide web browsingfunctionality), and the like. The libraries 820 may also include a widevariety of other libraries 848 to provide many other APIs to theapplications 816 and other software components/modules.

The frameworks/middleware 818 (also sometimes referred to as middleware)provide a higher-level common infrastructure that may be used by theapplications 816 and/or other software components/modules. For example,the frameworks/middleware 818 may provide various graphic user interfacefunctions, high-level resource management, high-level location services,and so forth. The frameworks/middleware 818 may provide a broad spectrumof other APIs that may be utilized by the applications 816 and/or othersoftware components/modules, some of which may be specific to aparticular operating system 802 or platform.

The applications 816 include built-in applications 838 and/orthird-party applications 840. Examples of representative built-inapplications 838 may include, but are not limited to, a contactsapplication, a browser application, a book reader application, alocation application, a media application, a messaging application,and/or a game application. Third-party applications 840 may include anapplication developed using the ANDROID™ or IOS™ software developmentkit (SDK) by an entity other than the vendor of the particular platform,and may be mobile software running on a mobile operating system such asIOS™M, ANDROID™, WINDOWS® Phone, or other mobile operating systems. Thethird-party applications 840 may invoke the API calls 808 provided bythe mobile operating system (such as operating system 802) to facilitatefunctionality described herein,

The applications 816 may use built-in operating system functions (e.g.,kernel 822, services 824, and/or drivers 826), libraries 820, andframeworks/middleware 818 to create tits to interact with users of thesystem. Alternatively, or additionally, in some systems, interactionswith a user may occur through a presentation layer, such as presentationlayer 814. In these systems, the application/component “logic” can beseparated from the aspects of the application/component that interactwith a user.

The term“processor” is intended to include multi-core processors 904 that maycomprise two or more independent processors (sometimes referred to as“cores”) that may execute instructions 910 contemporaneously. AlthoughFIG. 9 shows multiple processors 904, the machine 900 may include asingle processor 908 with a single core, a single processor 908 withmultiple cores (e.g., a multi-core processor), multiple processors 908,912 with a single core, multiple processors 908, 912 with multiplecores, or any combination thereof.

The memory/storage 906 may include a memory 914, such as a main memory,or other memory storage, and a storage unit 916, both accessible to theprocessors 904 such as via the bus 902.

The components 918 may include a wide variety of components to receiveinput, provide output, produce output, transmit information, exchangeinformation, capture measurements, and so on. The specific I/Ocomponents 918 that are included in a particular machine 900 will dependon the type of machine. For example, portable machines such as mobilephones will likely include a touch input device or other such inputmechanisms, while a headless server machine will likely not include sucha touch input device. It will be appreciated that the I/0 components 918may include many other components that are not shown in FIG. 9.

For example, a network106 or a portion of a network may include a wireless or cellular networkand the coupling may be a Code Division Multiple Access (CDMA)connection, a Global System for Mobile communications (GSM) connection,or other type of cellular or wireless coupling. In this example, thecoupling may implement any of a variety of types of data transfertechnology, such as Single Carrier Radio Transmission Technology(1xRTT), Evolution-Data Optimized (EVDO) technology, General PacketRadio Service (CPRS) technology, Enhanced Data rates for GSM Evolution(EDGE) technology, third Generation Partnership Project (3GPP) including3G, fourth generation wireless (4G) networks, Universal MobileTelecommunications System (UMTS), High Speed Packet Access (HSPA.),Worldwide Interoperability for Microwave Access (WiMAX.), Long TermEvolution (LTE) standard, others defined by various standard settingorganizations, other long range protocols, or other data transfertechnology.

“EPHEMERAL MESSAGE”, in this context, refers to a message 300 that isaccessible for a time-limited duration. An ephemeral message may be atext, an image, a video, and the like. The access time for the ephemeralmessage may be set by the message sender. Alternatively, the access timemay be a default setting or a setting specified by the recipient.Regardless of the setting technique, the message 300 is transitory.

“MACHINE-READABLE MEDIUM”, in this context, refers to a component,device, or other tangible media able to store instructions 910 and datatemporarily or permanently and may include, but is not limited to,random-access memory (RAM), read-only memory (ROM), buffer memory, flashmemory, optical media, magnetic media, cache memory, other types ofstorage (e.g., erasable programmable read-only memory (EEPROM)) and/orany suitable combination thereof. The term “machine-readable medium”should be taken to include a single medium or multiple media (e.g., acentralized or distributed database, or associated caches and servers)able to store instructions 910. The term “machine-readable medium” shallalso be taken to include any medium, or combination of multiple media,that is capable of storing instructions 910 (e.g., code) for executionby a machine 900, such that the instructions 910, when executed by oneor more processors 904 of the machine 900, cause the machine 900 toperform any one or more of the methodologies described herein.Accordingly, a “machine-readable medium” refers to a single storageapparatus or device, as well as “cloud-based” storage systems or storagenetworks that include multiple storage apparatus or devices. The term“machine-readable medium” excludes signals per se,

“COMPONENT”, in this context, refers to a device, physical entity, orlogic having boundaries defined by function or subroutine calls, branchpoints, APIs, or other technologies that provide for the partitioning ormodularization of particular processing or control functions. Componentsmay be combined via their interfaces with other components to carry outa machine process. A component may be a packaged functional hardwareunit designed for use with other components and a part of a program thatusually performs a particular function of related functions. Componentsmay constitute either software components (e.g., code embodied on amachine-readable medium) or hardware components. A “hardware component”is a tangible unit capable of performing certain operations and may beconfigured or arranged in a certain physical manner. In various exampleembodiments, one or more computer systems (e.g., a standalone computersystem, a client computer system, or a server computer system) or one ormore hardware components of a computer system (e.g., a processor or agroup of processors) may be configured by software (e.g., an applicationor application portion.) as a hardware component that operates toperform certain operations as described herein.

A hardware component may also be implemented mechanically,electronically, or any suitable combination thereof. For example, ahardware component may include dedicated circuitry or logic that ispermanently configured to perform certain operations. A hardwarecomponent may be a special-purpose processor, such as afield-programmable gate array (FPGA) or an ASIC. A hardware componentmay also include programmable logic or circuitry that is temporarilyconfigured by software to perform certain operations. For example, ahardware component may include software executed by a general-purposeprocessor 908 or other programmable processor. Once configured by suchsoftware, hardware components become specific machines (or specificcomponents of a machine 900) uniquely tailored to perform the configuredfunctions and are no longer general-purpose processors 908. It will beappreciated that the decision to implement a hardware componentmechanically, in dedicated and permanently configured circuitry, or intemporarily configured circuitry (e.g., configured by software) may bedriven by cost and time considerations. Accordingly, the phrase“hardware component”(or “hardware-implemented component”) should beunderstood to encompass a tangible entity, be that an entity that isphysically constructed, permanently configured (e.g., hardwired), ortemporarily configured (e.g., programmed) to operate in a certain manneror to perform certain operations described herein. Consideringembodiments in which hardware components are temporarily configured(e.g., programmed), each of the hardware components need not beconfigured or instantiated at any one instance in time. For example,where a hardware component comprises a general-purpose processor 908configured by software to become a special-purpose processor, thegeneral-purpose processor 908 may be configured as respectivelydifferent special-purpose processors (e.g., comprising differenthardware components) at different times. Software accordingly configuresa particular processor 908 or processors 904, for example, to constitutea particular hardware component at one instance of time and toconstitute a different hardware component at a different instance oftime.

Hardware components can provide information to, and receive informationfrom, other hardware components. Accordingly, the described hardwarecomponents may be regarded as being communicatively coupled. Wheremultiple hardware components exist contemporaneously, communications maybe achieved through signal transmission (e.g., over appropriate circuitsand buses) between or among two or more of the hardware components. Inembodiments in which multiple hardware components are configured orinstantiated at different times, communications between such hardwarecomponents may be achieved, for example, through the storage andretrieval of information in memory structures to which the multiplehardware components have access. For example, one hardware component mayperform an operation and store the output of that operation in a memorydevice to which it is communicatively coupled. A further hardwarecomponent may then, at a later time, access the memory device toretrieve and process the stored output.

Hardware components may also initiate communications with input oroutput devices, and can operate on a resource (e.g., a collection ofinformation). The various operations of example methods described hereinmay be performed, at least partially, by one or more processors 904 thatare temporarily configured (e.g., by software) or permanently configuredto perform the relevant operations. Whether temporarily or permanentlyconfigured, such processors 904 may constitute processor-implementedcomponents that operate to perform one or more operations or functionsdescribed herein. As used herein, “processor-implemented component”refers to a hardware component implemented using one or more processors904. Similarly, the methods described herein may be at least partiallyprocessor-implemented, with a particular processor 908 or processors 904being an example of hardware. For example, at least some of theoperations of a method may be performed by one or more processors 904 orprocessor-implemented components. Moreover, the one or more processors904 may also operate to support performance of the relevant operationsin a “cloud computing” environment or as a “software as a service”(SaaS). For example, at least some of the operations may be performed bya group of computers (as examples of machines 900 including processors904), with these operations being accessible via a network 106 (e.g.,the Internet) and via one or more appropriate interfaces (e.g., an API).The performance of certain of the operations may be distributed amongthe processors, not only residing within a single machine 900, butdeployed across a number of machines. In some example embodiments, theprocessors 904 or processor-implemented components may be located in asingle geographic location (e.g., within a home environment, an officeenvironment, or a server farm). In other example embodiments, theprocessors 904 or processor-implemented components may be distributedacross a number of geographic locations.

“PROCESSOR”, in this context, refers to any circuit or virtual circuit(a physical circuit emulated by logic executing on an actual processor908) that manipulates data values according to control signals (e.g.,“commands,” “op codes,” “machine code,” etc.) and which producescorresponding output signals that are applied to operate a machine 900.A processor 908 may, for example, be a central processing unit (CPU), areduced instruction set computing (RISC) processor, a complexinstruction set computing (CISC) processor, a graphics processing unit(GPU), a digital signal processor (DSP), an ASIC, a radio-frequencyintegrated circuit (RFIC) or any combination thereof. A processor 908may further be a multi-core processor having two or more independentprocessors 904 (sometimes referred to as “cores”) that may executeinstructions 910 contemporaneously.

“TIMESTAMP”, in this context, refers to a sequence of characters orencoded information identifying when a certain event occurred, forexample giving date and time of day, sometimes accurate to a smallfraction of a second.
